Laparoscopic thyroid surgery is now one of the latest advances in laparoscopic surgery. Its greatest advantage is not only minimally invasive but more importantly, aesthetically pleasing, with no surgical incision in the exposed neck of the patient. In addition to a large number of laparoscopic biliary surgery in China, it has been reported to be applied in gastrointestinal, thoracic and urological aspects. Our hospital has been used for thyroid surgery since 2001, and is in the leading position in this aspect in Tianjin. Typical case: The patient was a female, aged 27 years old. The operation took 2 hours and she was discharged on the 4th postoperative day with no surgical complications. Clinical data: The patient was a 27-year-old female. Complaint: A right anterior cervical mass was found for 2 weeks. Ultrasound confirmed that it was a single right thyroid mass. Equipment and methods: German STORZ laparoscopic equipment, intraoperative intravenous general anesthesia was used. The patient was placed in a flat position with a pillow behind the shoulder and the head slightly hyperextended, and a sterile towel was routinely disinfected. The anterior sternal approach was used, and a 1-cm-long incision was made at the anterior sternum in the line of both nipples. An epinephrine saline was injected under the superficial layer of the pectoralis major fascia cervicalis muscle, and a tunnel former was used to create a tunnel in this layer from the chest to the neck. Two additional holes of 0.5 cm and 1 cm were made on both sides of the areola to place the non-invasive grasping forceps and ultrasonic knife. The operating space is maintained by inflating the operative cavity with CO2 gas perfusion at a pressure of 5 mmHg. The ultrasonic knife was used to separate the deep surface of the broad cervical muscle to the surface of the anterior cervical muscle, and the cervical white line was cut longitudinally. The left anterior cervical muscle is transected with the ultrasonic knife, the thyroid tissue is incised, and the swelling is excised along the edge of the swelling with some of its surrounding normal thyroid tissue using the ultrasonic knife. The specimen was removed from the middle incision with a specimen bag, the transected left anterior cervical muscle and the cervical white line were sutured, and a silicone drainage tube was placed. The wound was glued with medical biologic adhesive. Results: The operation took 2 hours with no significant bleeding. Postoperative anti-inflammatory treatment was given for 3 days, and there was no postoperative fever. The drainage tube was removed at 48 hours postoperatively and the wound healed well. Postoperative pathology: thyroid adenoma. Precautions: 1. Operators and participants should be skilled in laparoscopic cholecystectomy and open thyroid surgery. 2. The correct selection of surgical indications is important. The object is benign masses of the thyroid gland. These include thyroid adenomas, thyroid cysts, etc. This surgery can also be used for primary or secondary hyperthyroidism with II degree enlargement. Indications for mass size generally advocate that a mass less than 5 cm is appropriate. The ideal patient for surgery is a thin body with no surgical injury or radiotherapy. 3. Contraindications to surgery include contraindications to general anesthesia, multiple thyroid masses, history of previous neck surgery, history of radiation therapy, short neck and especially obese patients, etc.
